Would you like to take a collagen cure to care for your skin and/or joints, but don't know which source to choose? We'll help you find out.
What is collagen?
Collagen is our body's most abundant protein, representing 30% of total proteins.
It's a protein naturally present in all our body's structures, such as skin, tendons, bones, cartilage and ligaments. This protein is essential for tissue maintenance and strength.
There are around 20 types of collagen in the human body, of which only 3 are predominant in the organism:
Type I collagen: the most abundant, mainly in tendons, bones, skin, ligaments and cornea.
Type II collagen: present in cartilage.
Type III collagen: present in muscles, internal organs and vessel walls.
Collagen has two main sources:
Bovine collagen, which comes from bones,
Marine collagen, which comes from the skin, cartilage or scales of fish.
Here's an overview of the advantages and disadvantages of each source.
Bovine collagen
The benefits of bovine collagen :
Because bovine collagen is of type I and III origin, it is particularly well-suited to skin care. In fact, this is the type of collagen used for injections.
Bovine collagen provides the body with glycine and proline, amino acids required for endogenous collagen production.
The disadvantages of bovine collagen :
It is poorly bioavailable
The carbon footprint of bovine collagen production is substantial,
There is a risk of microbiological contamination, particularly from the antibiotics and growth hormones fed to cattle,
Collagen quality can be altered by farming conditions.
Marine collagen
The benefits of marine collagen :
Marine collagen offers superior bioavailability, enabling the body to benefit more deeply from its effects.
Marine collagen is known to be rich in hydroxyproline, an amino acid essential for its synthesis.
Numerous studies have demonstrated theeffectiveness of marine collagen on joints, muscles and bones, as well as its antioxidant effect on the skin.
The disadvantages of marine collagen :
Marine collagen should be avoided by people allergic to fish.
Marine collagen is more expensive.
Marine collagen peptides from Laboratoire Dielen
Laboratoire Dielen has developed and patented an enzymatic hydrolysis process for cutting marine proteins into small, low molecular weight peptides.
This process makes our collagen peptides unique because :
The hydrolyzed form of our collagen peptides makes them easier to digest. As a result, their assimilation by the body is facilitated and even accelerated,
Leur efficacité a été démontrée cliniquement à faible dose grâce à leur bas poids moléculaire (<2000 daltons),
Their properties have been clinically demonstrated in 4 studies published in international journals.
